Ideal PB adsorbents for Cs removal should be able to spontaneously adsorb Cs+ ions without significant release of hexacyanoferrate fragments and can be stably stored in dry condition. This study synthesized poly(methyl methacrylate) (PMMA) beads using suspension polymerization with PB-rich shell as Cs adsorbents, which presents less than 2% water swelling in water and can be stored at dry condition. In batch and sand filter tests the PB-PMMA beads reveal spontaneous and endothermic Cs adsorption behavior with minimal release of the hexacyanoferrate fragments. ? 2018 Taiwan Institute of Chemical Engineers |
